Question 57 & 58

We use here our common sense to solve this question. i-e one cut will always give two pieces, (one number more than cut number) – is the start point! so 9 cuts will give 10 pieces. Then we will use unitary method to find the solution.And in this way the solution will be found!

Statrt:

Clearly one cut will divide the roll in two parts as shown in figure below:

So if the tailor cuts a roll into 10 pieces, then he will have to make 9 cuts!

It is given also that he can make 45 cuts in 1 minute:

So, in 24 minutes he will make 45×24= 1080 cuts!

It is also given that 1 roll takes 9 cuts of shirt pieces;

i-e

(i

(Above can be explained by saying that 9 cuts are equal to one roll – then divide both sides by 9, we get this equation saying 1 cut is equale to 1 over 9 rolls. Multiply both sides with 1080, then we get 1080 cuts equal to 120 rolls i-e 120 rolls will give us 1080 made in 24 minutes)
